PROBLEM TO BE SOLVED: To provide an acoustic matching material supply device capable of supplying a sufficient acoustic matching material between an ultrasonic probe and an object, and an ultrasonic probe unit, an ultrasonic measuring device, and an ultrasonic image display apparatus.SOLUTION: The acoustic matching material supply device includes a frame part that is mounted on an ultrasonic probe with an ultrasonic sensor surface for performing at least one of transmission and reception of ultrasonic waves, and that discharges an acoustic matching material. The frame part includes: an inner peripheral surface included on a surface crossing the ultrasonic sensor surface； a plurality of outlets provided at the inner peripheral surface or an area including the inner peripheral surface for discharging the acoustic matching material； an introduction port for introducing the acoustic matching material from the outside； and a passage for communicating the outlets with the introduction port.SELECTED DRAWING: Figure 2【課題】対象物との間に十分な音響整合材を供給可能な音響整合材供給装置、超音波プローブユニット、超音波測定装置、超音波画像表示装置を供給する。【解決手段】音響整合材供給装置は、超音波の送信及び受信の少なくとも一方がなされる超音波センサー面を含む超音波プローブに装着されて音響整合材を吐出する枠部を備え、枠部は、超音波センサー面に交差する面に含まれる内周面と、内周面又は内周面を含む領域に設けられて音響整合材を吐出する複数の吐出口と、前記音響整合材を外部から導入する導入口と、吐出口と導入口とを連通する流路と、を備える。【選択図】図２
